Users of physical or virtual machines commonly install software packages, including package updates, to those machines. The software packages can contain a set of related files chosen to perform a given application or task, such as, for example, a group of software applications, drivers, and/or other resources used to install and use messaging or media applications. In instances, a software package can contain application software, operating system software, drivers, patches, and/or other software components grouped as a logical set.
Software package managers exist to help a user initiate and perform software package updates, such as, for example, the “yum” (Yellowdog update manager) package update manager available from Red Hat Inc., and others. In general, available software package managers are configured to interact with the set of installed packages on a client and with one or more software package repositories and associated package servers, to directly connect to those databases and download available package updates.
The process of managing package installations and initiating software package updates can involve, however, a significant degree of processing overhead, including when the managed network in which the host or client machines are installed is large. In those and other cases, tracking the package complement on each host machine can involve a significant amount of storage, and/or a significant amount of communications overhead. In such conditions, the package server and/or other remote management platform may have to track, interrogate, send commands, or distribute downloads to thousands, hundreds of thousands, or greater numbers of host machines, so that querying or interrogating each machine or groups of machines can require a significant amount of bandwidth and time. In those large-scale and other network architectures, it would be advantageous to be able to consult a local or high-speed storage record of the package complements installed on a machine or groups of machines, without a need to communicate with those machines directly, and without a need to generate reports from a package repository each time an update or other management task is desired. It may be desirable to provide systems and methods for generating cached representations of an encoded package profile, in which a package server or other management platform can capture encoded identifications of package installations from client machines, and store those encoded package identifications to a local cache memory for rapid access for use in package updating, inventorying, and/or other management activities.
